The study of coronary angiography results in patients referred to coronary angiography laboratory of Shahid Beheshti Hospital from November 2010 to April 2011

This study was done to assess coronary artery angiography results in ACS patients referred to KashanShahidBeheshti hospital. Coronary artery disease is one of the most common diseases with the highest mortality rates in developed and developing countries. This is a cross-sectional study, which was conducted using existent data through convenience sampling of 435 patients. The data were gathered using patient's records using tools including questionnaires and checklist. Variables include age, sex, diagnosis, physician name, left ventricle ejection fraction, dominant side of perfusion of cardiac muscle, type of physician recommendation and involved vessels. Finally, data was statistically analyzed using SPSS software, 16.0. The results of this study showed 56.1% of cases had mild (non-pathological) disorder and others (43.9%) had a severe stenosis in their coronary arteries. Also, 21% of cases had three vessel disease. Also, left anterior descending artery (LAD) was more stenoticthan the other arteries. According to the results of this study and high frequencies of non pathologic cases, it is recommended that cheaper diagnostic methods such as accurate clinical examination get used for patient selection.
